Oscillators

The arrows between the oscillator select buttons show how the oscillators are

paired, as does the following table.

The effect of Sync is much more easily heard than explained. Here’s a simple

example of how to use Sync.

1. Load the Basic Patch from the Global menu. Oscillator 1 and 2 S

HaPe

is set

to sawtooth and oscillators 3 and 4 are off.

2. Turn oscillator 2 o

utPut

l

evel

to 0. Only oscillator 1 should be audible.

3. Turn oscillator 1 S

ync

on.

4. Now turn oscillator 1 P

itcH

while playing the keyboard. The harmonic

content changes, but not the fundamental pitch. Now do the same thing

while turning oscillator 2 P

itcH

. (Remember: only oscillator 1 should actu-

ally be audible.) The fundamental pitch changes, but the harmonic content is

relatively consistent. Oscillator 2 is the master and oscillator 1 is the slave.

Tip:

Use glide, an envelope generator, an LFO, the mod wheel, or other

modulation source to sweep the pitch of a slave oscillator.

Of course, each of the four oscillators can be synced, so it’s possible to have two

pairs of synced oscillators or to sync oscillators in series (an oscillator synced to

a synced oscillator, synced to a synced oscillator…).

Note:

The o

Scillator

1 S

uB

o

ctave

does not sync to oscillator 2. To sync

oscillator 1 and have a sub octave that plays in tune with oscillator 2, use one

of the other oscillators as a sub.

Output Level: 0…127—

Sets the output level for each of the oscillators.

Note:

When using three or four oscillators, it may be necessary to reduce the

levels of each to avoid clipping.
